I give that a try ... as I set up a fresh new btrfs-subvolume to do a |
4 |
fresh new build based on my <at> world only yesterday I will see if I can do |
5 |
it with gcc 4.9 while I am at it. |

|

Let's see if things work out and if it gets any better. |

Hello Stefan, |
11 |
|
12 |
Well. OK. I'm working on a fresh install of gentoo with btrfs. |
13 |
Subvolumes have me a bit mystified still. I mostly followed this |
14 |
doc for a basic (raid 1) configuration with btrfs: |
15 |
|

http://wiki.gentoo.org/wiki/Btrfs_native_system_root |
17 |
|
18 |
If you would be so cool as to post your subvolume setup; |
19 |
I'd be very grateful: |

I guess what really has me "confused" is to set up a traditional |
79 |
fstab, uuid, efi, with grub2. I'm just "dense" I guess |
80 |
because the aforementioned doc, I think derived from some |
81 |
of "Duncan's" postings just does not click for me. I've botched |
82 |
a few runs at btrfs (raid1) one on fresh gentoo installs, just |
83 |
so you know.... |
84 |
|
85 |
Your guidance is keenly appreciated. |
